I may be getting a totaled M3, an want to do the swap my self also. I have a few questions i was wondering if you could help me out with. Sorry if you had any of these answers in your thread, I may have skipped over them.

1. can i use the sub frames front and rear control arms an suspension?
2. how much of the wire harness do i need to transfer to sedan?
3. my car is already a manual would i still need to transfer pedal assembly?
4. Will the RPM lights work on the gauge cluster work, or what has to be done to make them work?
